Eichel was drafted by Buffalo back in 2015, but was never able to bring the Sabres back into contention. After sustaining a neck injury, his frustration with the club escalated as they wouldn't approve a higher technology surgery that he wanted.
Eichel seemed to have found his groove in Vegas, coming off a solid season that saw him score 27 goals and 39 assists in 67 games. In the playoffs, Eichel recorded 26 points in 22 games played on their way to winning the Stanley Cup.
